this is probably because we never 'speak' (although write) in programming languages trying to convey something

Have you told anyone to grep, cat, mount, fsck, or sudo?

I'd say the more experience one has with a programming language, the more reading and writing it feels like a natural language.

These are borrowings or coins into a natural language. A word from bash does not mean you are speaking bash any more than saying macaron would mean you are speaking French.
